Best fiber optic bead for 870

[Mossyballs]

I have an 870 12 ga turkey barrel with white front bead. What is best green fiber optic bead to replace my white bead. Still just a bead shooter but I want a small green bead as to not obscure turkey.

Magnum gobble dot pro, easily one of the best out there. FOV is great, try it you'll like it. http://www.truglo.com/firearms-turkey/pro-series-magnum-gobble-dot.asp
